[Example: )} 5 , 4 ( ), 2 , 3 ( ), 4 , 2 ( ), 3 , 1 {( ! ! = S ] * Domain : In a relation consisting of ordered pairs ( x , y ), the set of x -values is the domain. * Range : In a relation consisting of ordered pairs ( x , y ), the set of y -values is the range. 1. Identify the domain and range of the following: )} 2 , 9 ( ), 1 , 5 ( ), 3 , 1 ( ), 2 , 1 {( ! ! = S 2. Make a scatterplot of the relation )} 5 , 4 ( ), 2 , 6 ( ), 9 , 3 ( ), 4 , 0 {( ! = S . 3. Evaluate 1 5 ! = x y for 1 , 0 , 1 , 2 ! ! = x and 2.
